4 Claims.

My invention` relates to a new and useful irn-` provement in a safety razor and has for its object the provision of a safety razor Which will be compact, light, durable, simple in structure, economical to manufacture, easily and quickly assembled and disassembled and possessing a minimum number of parts.

Another object of the invention is the provision of a safety razor so constructed and arranged as 1o to reduce to a minimum and substantially prevent a clogging or" the razor when in use.

Another object of the invention is the provision of a safety razor adapted for use with a blade so constructed and arranged as to be highly flexible.

Other objects Will appear hereinafter.

The invention consists in the combination and arrangement of parts hereinafter described and claimed.

The invention will be best understood by a reference to the accompanying drawing which forms a part of this specification and in which:

Fig. 1 is a perspective View of the invention assembled for use,

Fig. 2 is a side elevational view of the invention showing the parts in separated relation,

3 is a sectional view taken on line 3 3 of Fig. 2,

Fig. 4 is a fragmentary enlarged sectional View,

Fig. 5 is a view taken on line 5 5 of Fig. 2, and

Fig. 6 is a plan view of the blade usedI with the invention.

It is preferred to form the parts of the razor 35 with the exception of the blade from a moulded material Which will be light and which may be of various colors such as the Well-known bakelite or similar fibrous compositions. The handle II is formed preferably integral with the guard plate l2 which is provided With a plurality of openings` i3 separated by the ribs Ill. Projecting inwardly of the openings I3 are teeth I5 which are of less height than the ribs I4. Extending longitudinally or the plate l2 at opposite sides of its. center are grooves I6. A backing plate or clamping member il is provided with a plurality oi spaced prongs l at opposite sides, adapted to engage in the grooves 5. The blade 2l is provided with a centrally located slot I8' and adjacent opposite ends of this central slot I8' and on opposite sides thereof are formed slots I9. These slots I9 are so spaced as to receive the prongs i3 and when the blade is positioned on the backing plate Il with the prongs projected through the slots I9, the backing plate With the (Cl. SI1-12) blade mounted thereon may be slid longitudinally of the groove I5 so that the prongs I8 will engage in the grooves and serve to prevent a removal of the backing plate or clamping member Il from operative relation to the guard I2 by any movement other than a longitudinal slidable movement. By virtue of the location of the slots I8' and I9, the blade is easily iiexed to conform to the shape determined by the member Il and the guard plate l2 so that a highly ilexible blade is, present and the points of iiexing are protected by the backing plate and the guard to afford the desired rigidity in the blade while shaving. As clearly apars in Fig. 4, the ribs I4 engage the under surface of the blade 2l Which does not project beyond the end of the guard plate. The teeth I5 are spaced from the under surface of the blade 27 to allovv clearance for lather and shavings and an enlarged opening 23 extending longitudinally of the guard plate I2 at opposite edges is positioned so that free passage of lather and shavings from the blade 21 is aiorded While in use, thus preventing a clogging of the razor.

It is thus seen that the razor comprises, in addition to the. blade, only a pair of separable parts which may be easily and quickly assembled or disassembled. When assembled, the resiliency of the blade 2l Will resist slidable movement of these parts so that accidental dislocation of the member Il relatively to the guard I2 is reduced to a minimum.

By forming the parts from composition material as described, an attractive article may be afforded as color contrasts on the various parts may be employed.

While I have illustrated and described the preferred form of construction, I do not Wish to limit myself to the precise details of structure shown, but desire to avail myself of such variations and modifications as come Within the scope of the appended claims.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. A safety razor comprising a handle; a head carried by said handle and projecting laterally from one end thereof, said head having at opposite sides of its medial line on its outer face a longitudinally extending groove; a backing plate; and spaced prongs on said backing plate engaging -in said grooves for retaining said backing plate on said head.

2. A safety razor comprising a handle; a head on one end of said handle and projecting laterally from opposite sides thereof, the outer face of said head being provided at opposite sides of its medial line with longitudinally extending grooves; a backing plate; spaced prongs projecting from one side of said backing plate on opposite sides of its longitudinal medial line and engageable in said grooves for securing said backing plate on said head. f

3. A safety razor comprising a handle; a head carried on one end of said handle and having a' plurality of spaced longitudinally extending grooves formed therein; teeth formed on opposite edges of said head; ribs on opposite edges of said head lying between said teeth, said teeth being of less height than said ribs; a backing plate; spaced means on said backing plate engageable in each of said grooves for retaining said backing plate on said headand effecting a pressing of a blade at its opposite edges against said nibs.

4. A safety razor comprising a handle; a head carried on one end of said handle and having a plurality of spaced longitudinally extending grooves formed therein; teeth formed on opposite edges of said head; ribs on opposite edges of said head extending between said teeth, said teeth being of less height than said ribs; a. backing plate; spaced means on said backing plate engageable in each of said grooves forvretaining said backing plate on said head and effecting a pressing of a blade at its opposite edges against said ribs, said head having an enlarged opening inwardly of said ribs and below the same.
